Restricted by the rolling terrains of mountainous areas in western parts of China, long steep downgrades are very common in mountainous freeways. Influenced by the factors like high altitude, big elevation differences, and the severe weather condition e.g. black ice, heavy snow and thick fog, most long steep downgrades turn to traffic accident prone sites. Moreover, once traffic accident happen...

Gonorrhoea continues to be a significant health challenge in Greenland. The aim of this study was to describe the development of gonorrhoea in Greenland through time including incidence rates and previous measures taken to address the challenge. A systematic literature search in PubMed, Embase and The Cochrane Library was conducted. Furthermore, local archives were searched in the Health Clinic...

The role of a photospheric component and of pair breakdown is examined in the internal shock model of gamma-ray bursts. We discuss some of the mechanisms by which they would produce anomalously steep low energy slopes, X-ray excesses and preferred energy breaks. Sub-relativistic comptonization should dominate in high comoving luminosity bursts with high baryon load, while synchrotron radiation ...

economic imbalances and social disparities are a common feature of developmenteconomies, particularly those which have historical antecedents of colonial rule. the study ofregional imbalances is given focus especially to southeast asian countries owing to its renewedimportance in the global order. post independent india had to tackle with several problems at theoutset, regional imbalance and ec...

The effects of different sources of carbon, nitrogen and some of trace elements on cultivation of Bacillus thuringiensis H14 were studied. Glucose, glycerol, sodium acetate, (NH4)2SO4, corn steep liquor, yeast extract, hydrolyzed casein, Ca2+, Mg2+ and Mn2+ were the main parameters evaluated by Plackett-Burman statistical method. All el...

Corn steep water as effluent which arrives in environment from starch processing industry has adverse effects on the environment and also large volume of fresh water is wasted. Corn step water is composed of high concentration of proteins, sugar, starch, vitamin and minerals, so it can be used as substrate for production of biological products. Hence, corn steep water concentration is important...

The population of the brown planthopper Nilaparvata lugens (Stål) in temperate regions is characterized by discrete periods of seasonal appearance, low initial density, steep and steady growth, clumped spatial distribution, and violent fluctuations from year to year. N. lugens, a temporary inhabitant, arrives from long distances barely in the ricegrowing season. Its high potential fecundity, hi...
